Answer:

x =22

Step-by-step explanation:

ABCD is a parallelogram. In parallelogram, adjacent angles are supplementary.

∠B +∠C = 180

4x + 12 + 3x + 14 = 180

Combine like terms

4x +3x + 12+ 14 = 180

7x + 26 = 180 {Subtract 26 from both sides}

7x = 180 - 26

7x = 154 {Divide both sides by 7}

x = 154/7

x = 22
